The new judicial interpretation of illegal evidence exclusion promulgated in 2017 has developed the exclusionary rule of illegal evidence in our country from the two aspects of substantiality and procedure. The interpretation refines the connotation of "illegal collection behavior", initially establishes the exclusionary rule of repeated confession, improves the system of procedural defense and further clarifies the leading role of the prosecution and courts in the exclusion procedures of the pretrial and trial stage. Because of the factors of the judicial system, it is undeniable that there still exist some structural problems in the exclusion of entity object; and in the procedural part, lawyers are still facing some institutional barriers in the procedural defense, the lack of sufficient participation of the suspects and their counsels in the pretrial stage and formalization of the procedure of exclusion in the trial stage, all of which require urgent resolution. In order to ensure the effective implementation of the exclusionary rule of illegal evidence, it is of great importance to strengthen the court’s independence, authority and impartiality fundamentally.
